下面是linux下安装apache的完整代码，系统是redhat5.5
下载httpd-2.2.6.tar.bz2 ?把httpd-2.2.6.tar.bz2放到/soft 下
[root@localhost ~]#cd /soft
[root@localhost soft]#tar jxvf httpd-2.2.6.tar.bz2 ? ?//解压apache的压缩包
[root@localhost soft]#cd httpd-2.2.6 ? ? //定位到httpd-2.2.6 文件夹下
[root@localhost httpd-2.2.6]#ls ? ? //查看显示httpd-2.2.6 文件夹下内容
[root@localhost httpd-2.2.6]#./configure --help | more ? ?//查看安装apache配置参数
[root@localhost httpd-2.2.6]#./configure ?--prefix=/usr/local/apache ?--enable-so ? ?// ?配置apache路径
[root@localhost httpd-2.2.6]#make ? ? //编译apache
[root@localhost httpd-2.2.6]#make install ? ?//安装apache
[root@localhost httpd-2.2.6]#cd /usr/local/apache ? //进入apache的目录 ? ??
[root@localhost apache]# ?cd conf/
[root@localhost conf]#cp -a httpd.conf httpd.conf- ? ? //备份apache配置文件
[root@localhost conf]#chkconfig ?--list httpd ? ? //查看httpd服务是否已存在
[root@localhost conf]#chkconfig httpd off ? ?//关闭系统自带了httpd的服务，如果存在httpd服务 ??
[root@localhost conf]#service httpd status ? ?//查看自带httpd服务状态
[root@localhost conf]#/usr/local/apache/bin/apachectl -k start ? ?//linux启动apache命令 ? ? ? ? ? ? ?
[root@localhost conf]#netstat -an | grep :80 ? ?//查看linux80端口是否开启
[root@localhost conf]#ps -aux | grep httpd ? ? //linux下查看apache进程
[root@localhost conf]#cd ../..
[root@localhost local]#cp /usr/local/apache/bin/apachectl /etc/rc.d/init.d/apache //拷贝apache启动脚本
[root@localhost local]#vi /etc/rc.d/init.d/apache ? ?// 这里是编辑apache启动脚本
? 在开头的#！/bin/sh ?下面加上
? ? ? ? ? ? ? #chkconfig: 2345 ?85 ?15
[root@localhost local]#chkconfig --add apache ? ?//添加apache服务
[root@localhost local]#chkconfig --list apache ? ?//列出apache服务
[root@localhost local]#service apache stop ? ?//停止apache服务
[root@localhost local]#netstat -an | grep :80 ? ? //查看linux的80端口是否关闭
[root@localhost local]#ps -aux | grep httpd ? ? //查看是否存在httpd服务，若果之前自带httpd服务启动的话会导致新添加的apache服务启动失败
[root@localhost local]#service apache start ? ?//启动apache服务
打开你的服务器ip地址，看看是否出现了tomcat的默认首页，如果出现的话，那么恭喜你
linux下安装apache已经成功了
